    window.exitonclick()





   

Question:




What does the last bit of Code do?




The last bit of Code which happens to be window.exitonclick() shuts down the window when you click. :)




The window variable is = to the turtle screen which displays the program itself. Python already knows what exitonclick means through built-in method retrievals.
